HORSE-COLLAR HAMMER.

SPECIFICATION forming part of Letters Patent No. 391,133, dated October 16, 1888.

Application filed February 2?, 1888. Serial No. 265,544.

To all whom, t may concern:

Beit known that I, W AsHINGroN FoGLn SONG, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Horse-Collar IIam mers; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaius to make and use he same.

My invention relates to horse-collar hammers, and has for its object to provide a construction which will give sharp elastic blows in rapid succession.

I have illustrated my invention in the accompanying drawings, and said invention is fully disclosed in the following specification and claims.

In the drawings, Figure l is a side View of my improved collar-hammer. Fig. 2 is a section on line :v x, Fig. l. Figs. 3, 4, 5, and 6 are detail views showing modied forms of my invention. Fig. 7 is a View showing the means by which the anvil is made adjustable.

In the drawings, A is the mainframe of the machine, mounted on a suitable base, B. The main frame may be hollow or solid, as preferred; but in either case it is provided with the recess a in the rear part of the same. Upon some portion of the frame, preferably at aA point adjacent to the recess a, are mounted, in any preferred manner, two standards, O O, the upper ends of which approach each other and are connected by a bolt, c. Upon the bolt c, as ajournal, is mounted the lever D, which is provided with two perforated ears, d d, near its center, to engage the journal, and upon the bolt c, between the two ears (Z d, is mounted the hammer-arm E. The hammer-arm may consist of one bar, as shown in Figs. 1, 3, 4, and 5; or it may consist of two connected parallel bars or of one bar provided with two parallel arms, as shown in Fig. 6.

The lever D is provided at its rear end with a smooth cylindrical portion,d, which terminatesin a cap or shoulder, cl2, and the opposite end is preferably provided with the two perforated circular projections d3.

In my preferred construction illustrated in Figs. 1 and 2 the hammer arm E has a (No modeli widened portion, e, directly under the earsd, which is provided with two slots or apertures. Through the ears d and the apertures in the part e of the hammer-arm pass the bolts F F, provided on their outer ends with nuts, and also provided at their lower ends with the washer H. Around the bolts are placed the spiral springs G G, one above and one below the hammer-arm, the slots in the part eofthe 6o hammer-arm being large enough to permit of vertical movement upon the bolts F. Imay, however, use but one bolt F, if preferred, and

I may also use but one spring G, and provide the portion e of the hammenarm with lugs to engage the coils of the spring in the center of the same.

In Figs. 3, 4, 5, and 6 I have illustrated modifications of my construction, in which I employ a dat steel spring instead of a spiral 7o spring, as in my preferred form.

In the form shown in Fig. 5 I employ one or two dat springs G, which are attached to the hammer-arm at or near the head of the hammer. The springs are secured at another point on the hammer-arm by passing through a staple, g, or two lugs provided on the arm, or in any other preferred manner. The other end of the spring G is then attached to the end of the lever D by means of alink or other con- 8o nection. By this means the same elasticity may be secured and very good results produced thereby.

In Fig. 4. I have shown a spring attached in this manner on both sides of thehammer-arm, and in Fig. 6 I have shown the hammer-arm, consisting for a portion of its length of two parallel bars and a single spring, attached to the hammer-arm, between the bars, in a similar manner. 9o

Fig. 3 represents a slightly different form of hammer, in which I inountthe hammer-arm on standards Cseparate from the standards O.

To the rear end of the hammer-arm is rigidly attached a flat steel spring, which is connected at its other end to the lever D by a suitable link. This construction also provides the elastic connection which, is necessary to give the hammer an elastic blow.

Upon the side walls of the recess a of the roo main frame is journaled the shaft K, which is provided with a crank or eccentric, k, between the bearings. This crank is connected, by means of a rod or pitman, L, with the sleeve M, which is mounted upon the cylindrical part d of the lever' D. This sleeve is provided with ears m, which engage the end of the connecting-rod or pitman, and also with a bind- Y ing-screw, m', which clamps the sleeve at any point upon the arm of the lever D.

Upon one end of the shaft K, outside of the main frame, is loosely mounted the bandpulley N, provided with a suitable clutch mounted rigidly upon the shaft, which is thrown into and ont of engagement with the band-pulley by means of a yoke, 0, on the end of the lever I?, which is mounted in brackets p, castor otherwise secured to the main frame A, and this lever passes through slots in the sides of the main frame to the opposite side of the-machine.

The end of the lever I? is connected,by means of a rod, p', to a foot lever or treadle, Q. This lever is preferably U-shaped, and embraces the base of the machine, extending aroundthe front side of the same, and its free ends are pivoted on both sides of the rear end of the frame.

The rod p is attached to the lever Q at apoint a little distant from the pivot upon that side of the frame, and the curved portion of the levervQ is held in a raised position above the iioor by a spring or other yielding device, and by this construction the lever may be operated from any part of the machine. Vhen the lever is depressed, it will draw down the rod 10', connected to one end of the lever P, which will also be depressed, thereby throwing the clutch into engagement with the bandwheel N,which is rotated constantly by means ofa driving-belt. The clutch will then cause 'the shaft to revolve with the band-wheel, and the crank or eccentric of the shaft will produce an oscillating movement of the lever D, which, by acting through the intervention of the springs G,will cause the hammer to strike the elastic blows upon material placed upon the anvil R, which is mounted upon the main frame under the head of the hammer.

The movement of thev lever D is not sufficient of itself to force the hammer down to the point at which the blow isto be delivered. Upon the first downward movement of the lever D the spring G above the hammer arm will be slightly compressed, and as the lever and hammer-arm are carried downward the inertia of the hammer and the force of the slight compression of the spring will carry the hammer down with a sharp elastic blow upon the material, which will effect a very slight compression of the spring G below the hammer-arm. The recoil of this lower spring will will tend to throw the hammer-arm u p immediately, even before the return movement of the crank-arm tends to raise it. It is a wellknown fact that for certain purposes a light sharp elastic blow from a hammer is preferable to a hard solid blow, andis in reality more effective, and it is this sharp elastic tap or blow which I effect by my construction.

While I have shown my operating mechanism as applied to my preferred construction of hammer-arm, it is obvious that it may be applied to the modified forms shown and described in the same manner.

The position of the sleeve M may be regulated upon the lever D to produce harder or lighter blows, as may be desired.

The anvil is preferably made adjustable by means of a screw construction, as shown in Fig. 7, or otherwise, so that it may be raised or lowered to accommodate material of different thickness or to regulate the force of the blow ofthe hammer, as may be desired.

While I have described my invention to be used for hammering collars, it may be used to hammer seams, nail boxes, and for any other purposes for which it may be found desirable.

In Fig. 5 I have shown the spring attached rigidly to the hammer-arm and connected to the vibrating arm D by a link. I may, however, prefer .to attach the spring rigidly to the vibrating arm and extend it to a point nearly over the head of the hammer and connect it thereto by a link, as shown in dotted lines.

What I claim, and desire to secure by Letters Patent, is f 1. In a leather-hammer, thecombination, with a vertically-adjustable anvil, ofa vibrating arm and a hammer-arm, the two being ,con`

nected by an elastic connection permitting the elastic movement of the hammer-arm toward and from the vibrating arm of a crank-shaft, and a pitman connecting the crank-shaft and vibrating arm, substantially as described.

2. In a leather-hammer, the combination, with a vertically-adjustable anvil, of a vibrating arm and a hammer-arm, the two being connected by an elastic connection permitting the elastic movement of the hammer-arm toward and from the vibrating arm of a crankshaft, and a pitman connectingthe crank-shaft and vibrating arm, the connection between the pitman and vibrating arm being adjustable toward andfrom the pivot of the vibrating arm, substantially as described.

3. In a leather-hammer, the combination,

with a pivoted hammer-arm, of a vibrating arm extending above said hammer-arm, two coiled springs interposed between the hammer-arm and the end of said vibrating arm, two rods, each passing through one of Said springs and through said hammer-arm, two coiled springs each encircling one of said rods between the hammer-arm and the end of the same, a washer on said rods and securing means, and a pitman and crank for operating said vibrating arm, substantially as described. In testimony whereof I aiiix my signature in presence of two witnesses.
